Floats and counterweights from BAMO are supplied with a magnet. They drive a Reed contact built in the ABS housing of BRT & BRK. Electric connections are on screw connectors. The switch is bistable; it stays in its new position once the float passed in front of it. The power switch is of 60 VA and it is recommended the use of a protecting relay (please see the documentation 250-01).
The BRK & BRT fit on the level guiding tube with a collar (plastic or stainless steel) that corresponds to diameters 32 mm or 63 mm. The high temperature BRT is available mostly for MAGTOP applications. Its housing is of aluminium and the unit will works up to 200°C.

Switching power: 60 VA / 23 V AC / 1 A
Reed contact: Bistable, NC and NO, 3 wires
Housing: ABS - aluminium for BRT version
Protection: IP 55
Temperature limits: BRK: -40°C to 80°C – BRT: -40°C to +200°C
Collar: Standard is stainless steel for Ø 32 or 63 (Ø 63 for BRT)

Respect the switching power limited at 60 VA.
Wiring diagram is on the housing.
Fit the contact (pressure cable gland to the bottom) with the collar.
Do not over-screw the collar.
Initialize a contact NO or NC with the float (or counterweight) making it driving up and down, to get the switch in the desired position.
Contact will be in the same position as indicated on the printed diagram.
